Linux a obtenu l'IP de DHCP, mais ne peut toujours pas se connecter au WPA2 WIFI
Ici, j'ai un problème.
J'ai un routeur sans fil qui est Buffalo WCR-HP-GN, et je configure un WIFI qui utilise l'authentification WPA2-PSK et la phrase secrète cryptée par TKIP. Le mot de passe est composé de 9 lettres.
Ma femme a un macbook et il peut se connecter au wifi. Mais mon lenovo x200 avec Ubuntu 12.04 LTS ne peut pas se connecter au wifi. J'ai vérifié le réglage et l'IP, tout va bien. Je peux obtenir l'IP via dhclient, mais lorsque j'essaie de ping la passerelle, cela ne fonctionne pas. Si j'essaie de le connecter avec un câble Ethernet filaire et que tout va bien, je peux ping la passerelle.
Quelqu'un peut-il me dire ce qui s'est passé et comment le résoudre? Merci !!
Voici le journal dmesg pendant que je me connecte au wifi.

J'essaie de comprendre le problème et j'ai constaté qu'il y a beaucoup de signal sur le même canal que j'utilise.Si je change de canal, je peux cingler l'IP du routeur. Je vais modifier cette réponse pendant que je peux obtenir un journal détaillé :)
Essayez de vous connecter sans fil, puis utilisez un autre appareil pour afficher la page du routeur et voir s'il répertorie votre hôte comme connecté.
En outre, je vois cela dans vos journaux:
192.168.11.3
S'agit-il de l'adresse IP attribuée à votre ordinateur? Si c'est le cas, essayez d'attribuer une adresse IP statique de votre routeur à l'adresse MAC de cet ordinateur, ou définissez l'IP statique dans Ubunt . Remplacez-le par un élément du domaine du routeur, tel que
192.168.11.13
(en supposant, bien sûr, que cette adresse IP n'est pas déjà prise)
